The gas supply to the heater must terminate in an isolation cock. This will allow the heater to be disconnected for
maintenance or repair.
All pipework must be supported and installed in accordance with the regulations listed on page 4 and to provide the
operating gas pressure and volume for the appliance. Pipes of a smaller size than the heater inlet gas connection
must not be used.
The final connection is made to the heater gas valve. This has an Rp 1/2" ISO 7 thread (1/2" B.S.P. internal thread).
A flexible metallic hose conforming to B.S. 6501: Part 1: 1991 (minimum specification type B Class 1) may be used
for this purpose. This must be kept clear of the flue products opening at the top of the heater.
Take care when making the final connection to the gas valve not to apply excessive turning force to the gas valve.
The valve inlet may be held using a 40mm spanner.
